iPhone constantly searching for signal and end up with No Signal

I have opened my iPhone 3GS to replace battery. I am not sure what was the damage I have done to my phone. After reassembly, it's searching for signal and finally says no signal. I gave the phone to local repair shop, they have tried changing the doc connector from a working phone but still no luck. I have made the small copper tooth near connector 7 touching the silver frame. Still no luck. I suspect connector 7 on the mother board is damaged. I have attached my mother board pics here. http://www.flickr.com/photos/79479917@N0...

looks more like the screw hole is damaged? might be the corner of the motherboard has been flexed and cracked the internal wiring from no7 to antenna reception or there is not good contact with the little gold pin on the top of the dock connector. this a 3G but the idea is similar.. http://www.mauron.net/iphonerepair/
